IMPROVEMENT IN PERMANENT-WAY ADJUSTERS.

' Specification forming part of Letters Patent No. 220,983, dated October 2S, 1879; application led- July l5, 1879; patented in France, October 19, v1878.

To all 'whom it may concern:

Be it known that I, JEAN BAPTISTE MEN- CIRE, of Contras, in the Republic of France, have invented a new and useful Permanent- Way Adjuster, which is fully set forth and described in the following specification.

The invention relates to a tool for adjusting the permanent way of railways, and may be used in the construction of new as well as for readjusting old lines.

In describing theinvention reference will be had to the accompanying dra\vings,which show an example of the new tool, Figure l being a plan, Fig. 2 a cross-section, C D, and Fig. 3 a longitudinal section, of the adjuster, while Fig. 4 slliows a key which forms an accessory to the too The adjuster con sists of a sin gle-armed curved lever, J, turning at one end on a horizontal axis lixed to a shoe or plate of sheet metal, A, strengthened by angle-irons T, while the other end ot' the lever forms the nut for a screw-spindle, K, placed nearly at a right angle to the lever, held at its lower end in a slot, c d, on the said shoe, and provided at its upper end with a suitable head, so as to enable the same to be turned by means of a key or lever,Fig. 4, in order to raisethe lever to which the nut is attached, or of which it forms a part.

The upper surface of the lever, which supports the rail to be elevated, is curved in such a manner as to avoid any sliding of the rail, and the lower surface of the shoe is made conveX, so as vto slide readily under the rail.

B is a washer; C, a guide; D, a steel plate between A and C 5 H, awedge. a b is the travel ofthe spindle K, (=146 millimeters c d, the length of the slot, (=180 millimeters;) fg, the

radius of the lever; o g h, the arc described by the axis of the spindle; m m', the inner, and m2 m3 the outer, end of the lever-face; a a',

the axis of the rail, (first position,) and n2 n3 the axis of the rail, (second position.) The drawings give also the most convenient di mensions for the various parts of the tool in millimeters.

Thetool can be worked by one or two men. After removing with a spade some earth from the base of the railwhere the tool is to be applied, the latter is inserted under the rail and the spindle turned, by means of the key, until the rail has reached the required height.

, Where the soil is very soft a plank may be placed under the shoe.

`Wlt I claim isl. The combination of a curved shoe with a hin ged lever and a screw-spindle, substantially as described and illustrated, and for the purpose set forth.

2. The construction of the shoe with a plate, A, of sheet metal, and a pair of angle-irons, T, substantially as described and illustrated. f
